Education and Transcendentalism Essay

Education is an important necessity that all people should have. Individuals need education for choosing their path in life and living on their own. People must possess the right knowledge and reason to do those things. Ralph Waldo Emerson and Tupac Shakur have both written articles with their views on education in the United States. Emerson’s â€Å"On Education† and Shakur’s â€Å"On the Topic of Education† have generally the same ideas. Emerson and Shakur convey their strong opinions about education to show that people should learn from their own experience and should not be learning unnecessary information. The best way to learn is from one’s own experiences. Learning from books is important; however, they don’t give an individual the full perspective of something. Emerson states, â€Å"This function of opening and feeding the human mind is not to be fulfilled by any mechanical or military method†¦ in education our common sense fails us, and we are continually trying costly machinery against nature† (Emerson). Individuals should be learning more from nature and personal experiences. This generation is too connected to technology to the point where people lose sight of the world around them. Nature gives one the knowledge they need. It makes it easier to learn when one visualizes and sees the world. Similar to Emerson, Shakur wrote that schools are â€Å"not getting us ready for today’s world†¦ that’s why the streets have taught me† (Shakur). Students generally don’t learn about life lessons in school. In other words, an individual gains the most knowledge from â€Å"the streets† or being outdoors and experiencing life through their own eyes. It is important to have book smarts but also street smarts and common sense. Without street smarts and common sense one will have a difficult time living on their own. A Transcendentalist theme that is similar to these ideas of Emerson and Shakur is valuing nature. Nature and the outside world give us knowledge that we can’t learn from books. Schools fail to teach students things that are truly important. Instead, they tend to repeat the same information. Shakur points out, â€Å"After you learn reading, writing, and arithmetic, that’s it. But what [teachers] tend to do is teach you reading, writing, and arithmetic, then teach you reading, writing, and arithmetic again, then again, just [making] it harder and harder† (Shakur). Once students learn the basics, they shouldn’t keep learning them over and over again. They should be learning other important things that exist in the world. Students should have classes for drugs and alcohol, crime, racism, and other important topics that exist in America. Shakur says, â€Å"I think it should be like college where you can go and take the classes that you want. I think that Elementary school should be that way, where they give you the classes you take, for the basics. And then Junior High School and High School should be the classes that you need, in order to choose your path† (Shakur). First, students beginning school should learn the basics. Then as they get older, students should learn the things that they need to help them decide what they want to do when they are on their own. But, schools today do not follow this method. Students should not be learning what they have already learned in the past. Basic information will always remain in individuals’ minds. In addition to not teaching the right and necessary information, teachers rely too much on memorization. Emerson states, â€Å"Nature loves analogies, but not repetitions† (Emerson). Learning comes from deep thought. Students should not be tested on their ability to memorize information. In most cases, memorizing information is not actual learning. Learning is acquiring knowledge not only through studying but also experience. Furthermore, nature learns in different ways rather than the same way. Therefore, students should not be learning things in the same way. They should be learning information in different perspectives. In other words, students should learn by reading, listening, visualizing, and experiencing to fully understand things. Emerson also said that students have â€Å"educated eyes in uneducated bodies† (Emerson). This means that students are not absorbing the information they are given. This information is being forced into the minds of students through reading books and listening to lectures that are usually boring and uninteresting. This is not the best way for students to learn. A Transcendentalist theme that is similar to these ideas is not only valuing nature but also simplifying one’s life. Simplifying one’s life is a theme because students should be learning only the things that they need and the things that will be useful to them later in life. Students should not acquire or possess unnecessary information just as people should not possess or be attached to unnecessary items. The minds of individuals should contain only the important things that will guide them through life. In â€Å"On Education† and â€Å"On the Topic of Education†, Emerson and Shakur express their opinion about school and education. Emerson believes that students should be learning more from nature and their own experiences. Also, memorizing information is not the proper way to learn because students don’t absorb the information well this way. Comparable to Emerson, Shakur believes that people gain the most knowledge when they are experiencing life and interacting with others. In addition, students shouldn’t be taught the same things repetitively but instead the significant things that will help them later in life. It is crucial that students are getting proper education. Most importantly, teachers have an obligation to help students obtain the necessary knowledge they need to succeed in life.

Under the Sea

One very hot summer day I went scuba diving in the ocean. It was so beautiful under the water. There were so many different kinds of fish, plants and other sea creatures. My favorite was a purple octopuses, a school of color full sea horses and of souse the most magnificent sea turtles. They were huge. One of them was even 3 times my size. I was so fascinated about the beauty of the sea, I lost track of time. As I was wondering around I suddenly came across a hidden city. In the middle of the entrance it looked like a board hanging with a name written on but, I could not make out the letters due to many years of fading.It was Like the city called me closer. As I entered the city I saw so many different kinds of tumbled down houses. There was small ground level ones and big double storage one's. I stumbled across what once was the mall. I absolutely loved It. I wish I could have been part of this magnificent city. Yes, It's true, everything was under water and old but It was so fascin ating. I wonder what happened to the people. At the very end of the city there was this gigantic palace. The king probably lived there. I decided to go and Investigate. As I swam in I was amazed. It was so beautiful in there and it was almost like the time Todd still.A faded red carpet welcomed me and at the side's there was statues which ended at the throne. Obviously I sat down. After pretending to be the Queen, I wondered through the palace. Each room had a different theme. Suddenly I heard a beep, it was the gas tank telling me I only had a few minutes of air left. I really did not want to go but I had no choice. On my way out I took a souvenir to remember this place. When I got home I told everyone of this hidden city, but no one would believe me. Looks like the city of wonders (that's what I called it) did not want to be found. Under the Sea One very hot summer day I went scuba diving in the ocean. It was so beautiful under the water.

Problems Human Service Clients are facing Essay

Clients are rarely dealing with just one issue at a time. Individuals, groups, and communities are facing a wide range of problems. These problems could range from housing needs, food, mental illness, drug abuse, or family issues, which may be difficult to deal with on just one level. Those individuals or groups and the problems they are facing are the reason why professional Human Service Helpers are needed in the world. In this paper, I will be discussing some of the problems the clients face and what helping skills human service workers use to assist the client with dealing with those issues and acquiring a better quality of life. The developmental perspective, according to the text, is described as human development being a continuous process and that there are certain phases and stages that individuals experience during their life span. (Woodside & McClam 2012) Even though every human will go through the 8 stages of life which is Basic trust vs. Basic mistrust; autonomy vs. sham e and doubt; initiative vs. guilt; industry vs. inferiority; identity vs. role confusion; intimacy vs. isolation; generativity vs. stagnation and ego integrity vs. despair, we don’t experience any of these stages the same. Erikson’s stage model is one of the many perspectives on the developmental of humans. For example, the basic trust versus basic mistrust means humans learn at the infant stage to trust in an environment that consistently provides for their needs. If a child did not receive adequate care as a child, human development may be affected causing issues later on in the future. Developmental tasks are addressed within the individuals’ social context and the context may not support individual development. (Woodside & McClam 2012). Using a developmental model to view the clients’ problems may help give the human service helper with a basic understanding of the process of growth and change that individuals normally experience. Some clients deal with issues like losing a job, natural disasters, accidents and major changes in life are often viewed in the situational perspective. These are problems that  occur because a client is in a particular place at a particular time. An example of situational perspective is a client at a group home for women was raped by a co- worker and was experiencing issues with trusting people which caused her to have issues with going to work and her work performance. She was experiencing anxiety, anger and shame. She was referred to a legal team and different agencies that helped her deal with the situation and allowed her to take responsibility of the situation and change it. Differences in behavior, customs and traditions can be problems the clients deal with and can cause situational problems as well. Another situation that could create major problems for clients are unemployment, this situation could easily cause psychological and physiological issues as well. This situation can cause economic difficulties that the whole family may have to face as a whole. Professional helpers can identify a client’s problem by establishing whether the client’s needs are being met. This theory is called the Hierarchical perspective which was described by Abraham Maslow but later divided into two categories: (D) deficiency needs and (B) being needs. (Woodside & McClam 2012) This perspective states that if a person is not able to meet their needs such as food and shelter, they will not be able to focus on other needs such as self esteem and independence. With problems such as child abuse, neglect or removing a child from a home, many of their physical, safety and self esteem needs may not be met and they will need help with getting these needs met in order to restore them to a supportive healthy environment. When needs are met, concern shifts to higher-order needs such as self esteem, independence and self actualization. (Woodside & McClam 2012) Within the societal perspective, problems are experienced by clients as a result of changes in the society that has left the client in an unfamiliar situation. A major societal problem that clients are dealing with is homelessness. I have learned that communities are experiencing homelessness on all levels due to high unemployment rates, mental illness and company downsizing and merging responsibilities now. The mental illness concerns are not being attended to adequately which is causing a lot of people to not be able to hold jobs, advance in jobs, etc. Some clients may turn to criminal beha vior to make ends meet which causes other problems like clients ending up in the criminal justice system. Other clients who may experience societal changes are veterans who are mentally ill and children  who are not able to take care of themselves and are relying on other clients whose dealing with societal issues themselves. These children clients are at a higher risk for domestic abuse, living with family who are dealing with substance abuse or mental health issues such as depression or anxiety. The environmental influence perspective emphasizes the importance of an individual’s environment on the person’s history, living situation and current problems they are experiencing. (Woodside & McClam 2012) Understanding the influences of the environment to the client will definitely be helpful when it comes to helping the client identify their problem. The most immediate influence on an individual are family which include parents interactions coming up in life, age and gender of siblings, and whether or not a parent or guardian was absent from the clients life. The client’s neighborhood could be an influence as well. These influences can determine a person thought process and problem solving abilities throughout life. For example if a child lives in an environment where the parents abused drugs, participated in gangs and crime, then more than likely those influences are going to stay with that child and they will grow up thinking it’s the norm to engage in that behavior. Problems can be viewed in many different perspectives and the range of problems a client has can occur at different stages in a client’s life span. The ranges of problems faced by clients are vast and unique to each individual, therefore it is imperative for the human service worker to understand each client and how each perspective relates to the client. Clients become part of the human service delivery system because they are experiencing a range of problems that has affected their quality of life. In most cases, there is never just one problem the client is facing, therefor the human service worker should be skilled in communication, listening, and problem-solving skills as well as knowledge of human needs.

NYC Subway Strike in 2005 Essay Example | Topics and Well Written Essays - 1250 words

NYC Subway Strike in 2005 - Essay Example On the other side, the transit workers have bigger wages than the teachers although their work is unqualified . In December 2005 the contract between Transport Workers Union and Metropolitan Transportations Authority expired so they had to sign another one. The two parts didn't agree because the Union asked wages too big and the MTA wanted to increase the retirement age from 55 to 62 and the retirement funds would have been reduced. These demands were considered unacceptable for the transit workers and MTA didn't drop out their requirements mostly because of the Taylor Law, which was very much used by the Metropolitan Authority during that period. The public employees fair employment(or the Taylor Law) defines the rights and obligations for public employees. If they have the right to organize and to elect their union representatives they are not allowed to strike. The fine for striking is twice the employees' salary for each day the strike lasts. MTA relied on this law and thought the workers will not strike. Christmas time was an important period for New York and the renewal of the contract overlapped with this moment. The Transport Workers Union took advantage of this, thinking that in this way they will obtain all their claims. The Union wanted raises of salary(6% per year for each of the five years of contract) , more expensive accommodation for maternity leave, finance for station maintenance , to lower the age of retirement from 55 to 66(while MTA wanted to raise it), improved health plans and a stronger pension fund. They didn't agree with the age of retirement or the percent for health insurance. One of the most intriguing demands of MTA was that the new workers should contribute to their pension plan with 6% of gross salary and to pay 1% for their health insurance and offered only 3.5% raise every year. However it should be specified that the average salary for a normal New Yorker is 45.000 dollars a year while that of an employee in public transportation is 51.000 dollars a year, with the mention that a bus or subway operator could earn even 63.000 dollars a year. During the strike seven million people were forced to go to work on foot or by bike , and the whole system almost collapsed .Some blamed the strikers for the crisis, saying that their wages are big enough for an unqualified work and some blamed MTA for taking advantage of the Taylor Law and having exaggerating demands. However 54% of the New Yorkers believed the complaints and requirements of the Union were fair and 36% didn't agree with it. The city was the one that suffered most from this crisis because all happened during the holidays and the tourist season when the city is like a throng. One thing is for sure none of the two parts didn't think at these. MTA thought they could ask anything because the Taylor Law would allow them and the Union speculated the period hoping that they will get what they want. The public response about who was responsible for the strike was once again divided: 41% said the both sides are guilty, 27% that MTA was to blame and 25% didn't agree with

Strategic Leadership Essay Example | Topics and Well Written Essays - 4000 words

Strategic Leadership - Essay Example This is the element of strategic leadership: a forward-thinking planning unit that accommodates current flexibility in design and operations to fulfill a future goal as it pertains to organizational success. This paper will highlight what strategic leadership means in today’s organizations as well as a discussion on the day-to-day relevance of strategic management as compared to organizational realities. The nature of strategic leadership Organisational leaders in a management role must consider systems integrity, maintain control over current operational function, and improve cultural and executive-level confidence in financial data when making decisions (Kittredge, 2009). Understanding how to move the organization forward means understanding what currently drives issues of production, staffing, human resources, marketing, and competitive position among competitors with similar product and service offerings in the external marketplace. Generally, this function is accomplished by performing external audits, such as Porter’s Five Forces Analysis or SWOT Analysis, to gain the understanding of consumer preferences as well as competitive activities designed to remove market share from the organization. In order to develop an effective future-based strategy, the current market position of the business and its internal operations and structure must be understood. Strategic leadership is then defined as first understanding product and customer profitability opportunities, how to develop effective marketing strategies, establish effective and compliance-based accounting strategies and also develop a total quality management system to guide current production or technologies designed to support the business. It is a form of management accounting that designs and evaluates performance against strategic analysis tools (Fung, 2006). Once these fundamentals of current business strategy are understood, a strategic leader then develops an appropriate mission or vision about how to achieve organizational goals over the long-term. Human capital is one of the most important elements of organizational success, thus a strategic leader understands the dynamics employee psychology and sociology in order to establish a culture of human loyalty toward achieving what has been spelled out in the mission or vision statement. A strategic leader, in order to achieve long-term goals, must understand what drives motivation in employee and management groups and then appeal to these needs in a variety of ways. Peacock (2008, p.44) identifies â€Å"just relying on yearly appraisals forces them to work in a pre-defined set of tasks without taking into account what they are capable of†. A strategic leader goes beyond simple performance analyses and works consistently to develop employees to be active contributors to meeting long-term goals as identified through new mission values and practices. Therefore, strategic leadership should be defined as not on ly achievement of future objectives toward organizational profitability, it should be seen as a transformational management style.

Not all Women experience oppression in a uniform way Research Paper

Not all Women experience oppression in a uniform way - Research Paper Example xperience, there is evidence that colored women have experienced the severest form of discrimination in countries such as Canada, and the White women are treated far much better. The history of gender disparities is historical and has punctuated the history of the world. Men have consistently resisted the struggle of women to take up senior positions within the community, and there is evidence that different societies have resisted differently. From this perspective, it is clear that different women have experienced oppression in different proportion and that men have been behind this ordeal. The idea that women are the enemies of their empowerment is acceptable to some extent but only contributes to a small proportion of the problems that women have encountered. Conventional politicians criticize the politics of sisterhood on different relative grounds. They argue that by encouraging women to identify their lives as shaped by patriarchal oppression, feminism has produced images of women being victims outside the forces which have consequently denied their critical involvement in most decision-making processes. Bacak (164) believes that by assimilating the differences between women into a sisterhood of common, shared experiences, power relations between women are under-theorized. Both limited and distorted analyzes of gender are in play. Convincingly, it is notable that contemporary feminists criticize the second wave of politics that promote women as victims (Crenwshaw, 2). The critique, in this case, frustrates the perceived inability of second wave feminists to explore and celebrate womens agency instead of presenting women entirely as victims of masculine prejudice. The critique stresses that women shared status as victims’ acts as a key rhetorical role in generating believes of unity and sisterhood. Nonetheless, Kirkland (89) notes a second wave of feminist driven ideology encourages a gender power relation predominantly altering the difference between men

Millennium Pest Control Services - Case Study Example Having completed this initial and important part of the marketing strategy, the firm is now in the process of configuring the value, set the price, communicate the set values to the prospective customers and deliver the values to the utmost satisfaction of the customers. "Consumer-focused marketing is the single most important factor that determines the success of an enterprise. Marketing is not just about selling. It requires a clear and astute understanding of what consumers want and the ability to deliver it to them through the most appropriate channels for a profit. It includes the planning, pricing, promotion and distribution of products and services for consumers, both present and potential." (Katherine Adam, Radhika Balasubrahmanyam, and Holly Born 1999) In today's competitive business environment, achieving the organizational twin objectives of maximizing the revenues and minimizing the costs depends entirely on the organisation's ability to improve upon the technical excellence by adopting innovative methods and improving the value of the products being offered to the customers. At the same time, adopting innovative techniques of production will lead to the creation of organizational values. It is very essential for a firm to constantly aim at the configuration of its value. "Configuring value means defining, creating, branding and pricing the offer" (Mark, 2004) While, the processes of defining and creating values are the crucial tasks in the success of any business, the processes of branding and pricing can be attempted with ease once a proper value is defined and created. The value configuration is a process by which the firm aims to create and occupy an unforgettable place for its products in the minds of the customers. The value configuration describes the ways by which value is created by the company for its customers and the ways by which such creation of value is exhibited as a reflection on the quality of the firm's products and services. This can be achieved by providing the customers the superior quality of the products or services, backed by the after sales services if required. Most of the firms forget the utility and value of the 'after sales service' as an important tool for gaining the brand loyalty. Thus the process of value creation encompasses managing quality in the entire chain of processes until the stage of the final co mpletion of the production or rendering of a service. To define organizational value is a difficult task, as the term takes different connotations under different circumstances depending on the perspectives to which it relates. It can be said that the best known value configuration is the value chain. While Porter's value chain framework (1985) is generally accepted as the common language for representing and analyzing the logic of firm-level value creation, Mark Gabbot (2004) presents the framework of value as an alternative to the traditional 4Ps approach. Adding value to the services and products in an organization is entrusted to the operations management for evolving suitable operational strategies to achieve higher value for the products and services. An organization may adopt all or any of the following strategies for value creation: Trying out different

Health Care Provision and Poverty Essay Example | Topics and Well Written Essays - 1000 words

Health Care Provision and Poverty - Essay Example This is not the case as the entire blame lies on the government which has for the longest time possible ignored the plights of the poor in relation to health care provision. Matters of insurance and health care heavily impacts on the poor as they are the minority in the nation and, therefore, cannot have access to such services. It is common knowledge that lack of access to proper medical aid at the appropriate time can only lead to more suffering of the patient. According to analysts, healthcare has become unaffordable for businesses and individuals because of varied reasons. The most prominent reasons for lack of health care services are poverty, lack of employment, and employers transfer of healthcare costs to their employees. The burden of health care is not any better for the employed Americans. These employed people have to pay more out of their pockets for medical services and doctor visits. Employed people contribute towards health care in the form of taxes which is deducted from their salaries on a monthly basis. The major reason for lack of health care for the employed is that health care has become too expensive, and families opt to keep the matters of health care on hold. Culturally, the cost of health care services should be on the employing unit and not the worker. An employer should never put more on an employee through health care as these can lead to high employee turnover. In as much as employers may not have adequate funds to support the health care programs, it is their duty to ensure that employees have access to proper medical services. Most Americans give priority to the provision of other basic needs like food, clothing, and home. Healthcare comes in as a secondary need and people will struggle to provide for it in times of need. There is a high death rate for Americans as they fail to have access to medical aid at the appropriate time or when they fall sick, they have no sufficient funds to cater for the medical need. Records of America ns way of spending indicate that their priority bills are mortgage, rent, car payments, and other adulthood obligations. People do not give health care priority because it is expensive to maintain an insurance cover especially for the entire family. With this in mind, it is only fair that the government takes up some responsibilities like provision of free health care to its citizens. Analysts believe that this will be instrumental in maintaining America’s image as one of the wealthiest and industrialized nation (Doug, 2010, pg 12). Health care services become an even extreme case for the unemployed. Insurance is a luxury for Americans with no jobs or who have just lost their jobs recently. Reports on channel 7 news showed the relationship between unemployment and free health care clinics. The rise of unemployment level in America has seen the growth of free health care clinics. The only obstacle in this case is the crowding in these health care clinics as most people are une mployed (Andrews, 2011, pg 40). In addition, the free health care clinics will only serve people who have current insurance cover. This idea cuts out so many people from using their services as most people in America have no cover because of its cost. Another option for the unemployed Americans is cobra subsidy policy, which caters for 65% of the whole bill. This is subject to people accepting to pay more after fifteen

Film analysis paper Essay Example | Topics and Well Written Essays - 750 words

Film analysis paper - Essay Example The final concept is Zoe’s lack of openness to the therapist. These concepts will be explored in the film, and their application in the film will be determined. The consequences of this concept to the relationship will be determined (Lanham and Rowman 5). The most evident concept seen in this film is Zoe’s sex addiction. Sex addiction is the escalating and persistence in sexual engagement in spite of an increase in negative consequences to others or oneself. Just like another addiction efforts to stop this addiction can be in vain. This concept of sex addiction is observed in the initial scenes of the movie, right after Zoe visits Quinton Canosa. During her visit, she gets attracted to Quentin, the owner of Quinton Canosa. Their first meeting begins, and this is even more evident when Zoe takes the contract papers to him to sign for the beginning of their business partnership. Interestingly, this turns out to be a sexual connection for them (Lanham and Rowman 12). The concept of sex addiction is well applied in the film. Zoe is not fully satisfied with her husband and instead of talking things out she decides to look for comfort elsewhere. Zoe often meets up with Quinton where she finds the satisfaction of her addiction. She does this over and over, and even spends time at work thinking about her meetings with Quinton. It  affects her devotion to her career during one time she is set to meet with a client at a hotel, but she fails to turn up on time. She then arrives very late when the client is leaving and lies that her daughter fell sick. Addiction consequently affects Zoà «Ã¢â‚¬â„¢s relationship with her kids since she even misses out on occasions that are important to her children with excuses of being sick and sometimes having a lot of work in the office. However, this constant meeting with Quinton increases her addiction. She one time

Cloud Computing Essay Example for Free

Cloud Computing Essay * Integrated development environment as a service (IDEaaS) In the business model using software as a service, users are provided access to application software and databases. The cloud providers manage the infrastructure and platforms on which the applications run. SaaS is sometimes referred to as â€Å"on-demand software† and is usually priced on a pay-per-use basis. SaaS providers generally price applications using a subscription fee. Proponents claim that the SaaS allows a business the potential to reduce IT operational costs by outsourcing hardware and software maintenance and support to the cloud provider. This enables the business to reallocate IT operations costs away from hardware/software spending and personnel expenses, towards meeting other IT goals. In addition, with applications hosted centrally, updates can be released without the need for users to install new software. One drawback of SaaS is that the users data are stored on the cloud provider’s server. As a result, there could be unauthorized access to the data. End users access cloud-based applications through a web browser or a light-weight desktop or mobile app while the business software and users data are stored on servers at a remote location. Proponents claim that cloud computing allows enterprises to get their applications up and running faster, with improved manageability and less maintenance, and enables IT to more rapidly adjust resources to meet fluctuating and unpredictable business demand.[2][3] Cloud computing relies on sharing of resources to achieve coherence and economies of scale similar to a utility (like the electricity grid) over a network.[4] | This article may contain original research. Please improve it by verifying the claims made and adding references. Statements consisting only of original research may be removed. (January 2013)| The origin of the term cloud computing is obscure, but it appears to derive from the practice of using drawings of stylized clouds to denote networks in diagrams of computing and communications systems. The word cloud is used as a metaphor for the Internet, based on the standardized use of a cloud-like shape to denote a network on telephony schematics and later to depict the Internet in computer network diagrams as an abstraction of the underlying infrastructure it represents. The cloud symbol was used to represent the Internet as early as 1994.[5][6] The underlying concept of cloud computing dates back to the 1950s, when large-scale mainframe became available in academia and corporations, accessible via thin clients / terminalcomputers. Because it was costly to buy a mainframe, it became im portant to find ways to get the greatest return on the investment in them, allowing multiple users to share both the physical access to the computer from multiple terminals as well as to share the CPU time, eliminating periods of inactivity, which became known in the industry as time-sharing.[7] In the 1990s, telecommunications companies, who previously offered primarily dedicated point-to-point data circuits, began offering virtual private network (VPN) services with comparable quality of service but at a much lower cost. By switching traffic to balance utilization as they saw fit, they were able to utilize their overall network bandwidth more effectively. The cloud symbol was used to denote the demarcation point between that which was the responsibility of the provider and that which was the responsibility of the users. Cloud computing extends this boundary to cover servers as well as the network infrastructure.[8] As computers became more prevalent, scientists and technologists explored ways to make large-scale computing power available to more users through time sharing, experimenting with algorithms to provide the optimal use of the infrastructure, platform and applications with prioritized access to the CPU and efficiency for the end users.[9] John McCarthy opined in t he 1960s that computation may someday be organized as a public utility. Almost all the modern-day characteristics of cloud computing (elastic provision, provided as a utility, online, illusion of infinite supply), the comparison to the electricity industry and the use of public, private, government, and community forms, were thoroughly explored in Douglas Parkhills 1966 book, The Challenge of the Computer Utility. Other scholars have shown that cloud computings roots go all the way back to the 1950s when scientist Herb Grosch (the author of Groschs law) postulated that the entire world would operate on dumb terminals powered by about 15 large data centers.[10] Due to the expense of these powerful computers, many corporations and other entities could avail themselves of computing capability through time sharing and several organizations, such as GEs GEISCO, IBM subsidiary The Service Bureau Corporation (SBC, founded in 1957), Tymshare (founded in 1966), National CSS (founded in 1967 and bought by Dun Bradstreet in 1979), Dial Data (bought by Tymshare in 1968), and Bolt, Beranek and Newman (BBN) marketed time sharing as a commercial venture. The development of the Internet from being document centric via semantic data towards more and more services was described as Dynamic Web.[11] This contribution focused in particular in the need for better meta-data able to describe not only implementation details but also conceptual details of model-based applications. The ubiquitous availability of high-capacity networks, low-cost computers and storage devices as well as the widespread adoption of hardware virtualization, service-oriented architecture,autonomic, and utility computing have led to a tremendous growth in cloud computing.[12][13][14] After the dot-com bubble, Amazon played a key role in the development of cloud computing by modernizing their data centers, which, like most computer networks, were using as little as 10% of their capacity at any one time, just to leave room for occasional spikes. Having found that the new cloud architecture resulted in significant internal efficiency improvements whereby small, fast-moving two-pizza teams (teams small enough to be fed with two pizzas) could add new features faster and more easily, Amazon initiated a new product development effort to provide cloud computing to external customers, and launched Amazon Web Service (AWS) on a utility computing basis in 2006.[15][16] In early 2008, Eucalyptus became the first open-source, AWS API-compatible platform for deploying private clouds. In early 2008, OpenNebula, enhanced in the RESERVOIR European Commission-funded project, became the first open-source software for deploying private and hybrid clouds, and for the federation of clouds.[17] In the same year, efforts were focused on providing quality of service guarantees (as required by real-time interactive applications) to cloud-based infrastructures, in the framework of the IRMOS European Commission-funded project, resulting to a real-time cloud environment.[18] By mid-2008, Gartner saw an opportunity for cloud computing to shape the relationship among consumers of IT services, those who use IT services and those who sell them[19] and observed that organizations are switching from company-owned hardware and software assets to per-use service-based models so that the projected shift to computing will result in dramatic growth in IT products in some areas and significant reductions in other areas.[20] On March 1, 2011, IBM announced the Smarter Computing framework to support Smarter Planet.[21] Among the various components of the Smarter Computing foundation, cloud computing is a critical piece. [edit] Similar systems and concepts Cloud computing shares characteristics with: * Autonomic computing — Computer systems capable of self-management.[22] * Client–server model — Client–server computing refers broadly to any distributed application that distinguishes between service providers (servers) and service requesters (clients).[23] * Grid computing — A form of distributed and parallel computing, whereby a super and virtual computer is composed of a cluster of networked, loosely coupled computers acting in concert to perform very large tasks. * Mainframe computer — Powerful computers used mainly by large organizations for critical applications, typically bulk data processing such as census, industry and consumer statistics, police and secret intelligence services, enterprise resource planning, and financial transaction processing.[24] * Utility computing — The packaging of computing resources, such as computation and storage, as a metered service similar to a traditional public utility, such as electricity.[25][26] * Peer-to-peer — Distributed architecture without the need for central coordination, with participants being at the same time both suppliers and consumers of resources (in contrast to the traditional client–server model). * Cloud gaming Also known as on-demand gaming, this is a way of delivering games to computers. The gaming data will be stored in the providers server, so that gaming will be independent of client computers used to play the game. [edit] Characteristics Cloud computing exhibits the following key characteristics: * Agility improves with users ability to re-provision technological infrastructure resources. * Application programming interface (API) accessibility to software that enables machines to interact with cloud software in the same way the user interface facilitates interaction between humans and computers. Cloud computing systems typically use REST-based APIs. * Cost is claimed to be reduced and in a public cloud delivery model capital expenditure is converted to operational expenditure.[27] This is purported to lower barriers to entry, as infrastructure is typically provided by a third-party and does not need to be purchased for one-time or infrequent intensive computing tasks. Pricing on a utility computing basis is fine-grained with usage-based options and fewer IT skills are required for implementation (in-house).[28] The e-FISCAL projects state of the art repository[29] contains several articles looking into cost aspects in more detail, most of them concluding that costs savings de pend on the type of activities supported and the type of infrastructure available in-house. * Device and location independence[30] enable users to access systems using a web browser regardless of their location or what device they are using (e.g., PC, mobile phone). As infrastructure is off-site (typically provided by a third-party) and accessed via the Internet, users can connect from anywhere.[28] * Virtualization technology allows servers and storage devices to be shared and utilization be increased. Applications can be easily migrated from one physical server to another. * Multitenancy enables sharing of resources and costs across a large pool of users thus allowing for: * Centralization of infrastructure in locations with lower costs (such as real estate, electricity, etc.) * Peak-load capacity increases (users need not engineer for highest possible load-levels) * Utilisation and efficiency improvements for systems that are often only 10–20% utilised.[15] * Reliability is improved if multiple redundant sites are used, which makes well-designed cloud computing su itable for business continuity and disaster recovery.[31] * Scalability and elasticity via dynamic (on-demand) provisioning of resources on a fine-grained, self-service basis near real-time,[32] without users having to engineer for peak loads.[33][34] * Performance is monitored, and consistent and loosely coupled architectures are constructed using web services as the system interface.[28] * Security could improve due to centralization of data, increased security-focused resources, etc., but concerns can persist about loss of control over certain sensitive data, and the lack of security for stored kernels.[35] Security is often as good as or better than other traditional systems, in part because providers are able to devote resources to solving security issues that many customers cannot afford.[36] However, the complexity of security is greatly increased when data is distributed over a wider area or greater number of devices and in multi-tenant systems that are being shared by unrelated users. In addition, user access to security audit logs may be difficult or impossible. Private cloud installations are in part motivated by users desire to retain control over the infrastructure and avoid losing control of information security. * Maintenance of cloud computing applications is easier, because they do not need to be installed on each users computer and can be accessed from different places. The National Institute of Standards and Technologys definition of cloud computing identifies five essential characteristics: On-demand self-service. A consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with each service provider. Broad network access. Capabilities are available over the network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, tablets, laptops, and workstations). Resource pooling. The provider’s computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to consumer demand. Rapid elasticity. Capabilities can be elastically provisioned and released, in some cases automatically, to scale rapidly outward and inward commensurate with demand. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be appropriated in any quantity at any time. Measured service. Cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported, providing transparency for both the provider and consumer of the utilized service. —National Institute of Standards and Technology[4] On-demand self-service See also: Self-service provisioning for cloud computing services and Service catalogs for cloud computing services On-demand self-service allows users to obtain, configure and deploy cloud services themselves using cloud service catalogues, without requiring the assistance of IT.[37][38] This feature is listed by the National Institute of Standards and Technology (NIST) as a characteristic of cloud computing.[4] The self-service requirement of cloud computing prompts infrastructure vendors to create cloud computing templates, which are obtained from cloud service catalogues. Manufacturers of such templates or blueprints include Hewlett-Packard (HP), which names its templates as HP Cloud Maps[39] RightScale[40] and Red Hat, which names its templates CloudForms.[41] The templates contain predefined configurations used by consumers to set up cloud services. The templates or blueprints provide the technical information necessary to build ready-to-use clouds.[40] Each template includes specific configuration details for different cloud infrastructures, with information about servers for specific tasks such as hosting applications, databases, websites and so on.[40] The templates also include predefined Web service, the operating system, the database, security configurations and load balancing.[41] Cloud consumers use cloud templates to move applications between clouds through a self-service portal. The predefined blueprints define all that an application requires to run in different environments. For example, a template could define how the same application could be deployed in cloud platforms based on Amazon Web Service, VMware or Red Hat.[42] The user organization benefits from cloud templates because the technical aspects of cloud configurations reside in the templates, letting users to deploy cloud services with a push of a button.[43][44] Cloud templates can also be used by developers to create a catalog of cloud services.[45] [edit] Ser vice models Cloud computing providers offer their services according to three fundamental models:[4][46] infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS) where IaaS is the most basic and each higher model abstracts from the details of the lower models. In 2012 network as a service (NaaS) and communication as a service (CaaS) were officially included by ITU (International Telecommunication Union) as part of the basic cloud computing models, recognized service categories of a telecommunication-centric cloud ecosystem.[47] Infrastructure as a service (IaaS) See also: Category:Cloud infrastructure In the most basic cloud-service model, providers of IaaS offer computers physical or (more often) virtual machines and other resources. (A hypervisor, such as Xen or KVM, runs the virtual machines as guests.) Pools of hypervisors within the cloud operational support-system can support large numbers of virtual machines and the ability to scale services up and down according to customers varying requirements. IaaS clouds often offer additional resources such as images in a virtual-machine image-library, raw (block) and file-based storage, firewalls, load balancers, IP addresses, virtual local area networks (VLANs), and software bundles.[48] IaaS-cloud providers supply these resources on-demand from their large pools installed indata centers. For wide-area connectivity, customers can use either the Internet or carrier clouds (dedicated virtual private networks). To deploy their applications, cloud users install operating-system images and their application software on the cloud infrastructure. In this model, the cloud user patches and maintains the operating systems and the application software. Cloud providers typically bill IaaS services on a utility computing basis: cost reflects the amount of resources allocated and consumed. Examples of IaaS providers include Amazon CloudFormation, Amazon EC2, Windows Azure Virtual Machines, DynDNS, Google Compute Engine, HP Cloud, iland, Joyent,Rackspace Cloud, ReadySpace Cloud Services, and Terremark.

Design Of A Pipe Climbing Robot Engineering Essay

Design Of A Pipe Climbing Robot Engineering Essay This technical paper explains the design process and simulation of a concept vehicle to drive inside a circular pipe of the desired configuration as shown in figure 1. The design is developed to facilitate; pipe climbing and carry an inspection of an inspection panel. This vehicle when operated will travel in a horizontal section of pipe initially, before entering the inclined part of the circular pipe. It then drives within 0.2m of the inspection panel and starts inspecting it with the help of an on-board camera. Specific equations and assumptions are used to monitor vehicle motion and system controllers are designed to enforce there is enough traction applied by the vehicle to grip the pipe and move forward. Figure 1 Pipe inspection Scenario Index Terms-design, linear actuators, multi-wheel drive, proximity sensor, robots Introduction Inspection and maintenance are essential in all industries. Failure to conduct proper maintenance could result in potential danger to workers and machines. Carrying out these inspections impose rigours hurdles in case of various industries where the conditions are unsafe for human workers, for example, inspection and maintenance in a nuclear industry, where the environment poses serious risk for the humans. The most common way for conducting these inspections in hazardous conditions is to use long manipulators which could be expensive. The alternate way of carrying these inspections is by using walking/climbing robots. Pipe climbing robots are advanced robots, which have the potential to climb inside/outside of a pipe to perform specific functions, where a normal operator cannot be used. The improvements in this sector have grown rapidly, since its a cheap and effective way for investigating various properties inside a pipe. An assignment has been assigned to design a concept vehicle to drive inside a circular pipe as in fig 1. This vehicle needs to enter the tunnel and drive to within 0.2m of the inspection panel and inspect the panel at the end of pipe. The vehicle must also carry a wire which is tethered. The climbing robots can be classified into four major categories based on their approach to climbing: adhesive, brute force fixture, spines and grasp. The robots with adhesive approach use a mechanism such as suction or an electromagnetic fixture on the climbing surfaces. The brute force robots use a mechanism to grab on to the structure and move forward. The spine group of robots use spines/multi-spines to attach themselves to the climbing surface so as to propel forwards. The last group of grasp robots use their own dynamic and kinematic state to grasp on to the engineering structure and moves forward. The present conceptual design can be categorised under grasping group of climbing robots. These robots consist of mainly two mechanisms, one to power the robot to move and the other to grip the surface of the structure. The mechanisms used to grip on to the surface can be facilitated by the usage of spring and v-shaped arm or longitudinal actuators. A v-shaped arm along with a compression spring is connected to the body of the robot. The compression springs tends to expand the arms, if the outer arm reaches the surface, it exerts a force normal to the contact of surface thus proving the traction for gripping the surface. In case of linear actuators various mechanisms are used to produce the linear motion of the arms to exert force onto the surface. The present design employs a linear actuator. It has longitudinal arms connected to linear actuators. The linear actuator is a simple rack-pinion mechanism, but consists of three racks to synchronise the outward motion equally in all three directions, thus providing an equal amount of force on each surface of the structure. A multi-wheel drive system is employed for the present case, as there is a need for requirement for more torque when the robot climbs the inclination part and to reduce the slip generated by the wheel. In the present case, the robot has five wheels and hence five individual motors, two on the bottom of the base, one on either side of robot and one at the top of the robot. When in operation the outer end of the wheels on all directions would be perfectly inscribed in a circle of 200cm when looked at front view. This mechanism coupled with linear actuators makes sure that at any instant all the wheels are in contact with the surface of the pipe thus providing maximum available traction for the robot. Robot model and modelling assumptions In the present concept of design the circular pipe is considered to be even and has a constant coefficient of friction throughout. Designing the robot requires a methodological approach to implement a professional structured robot is done by generating a CAD model of the robot. The components of the robot are selected with maximum care with feasible materials, since theoretical tests and scenarios can be modelled based on weight and dimension of the robot. After selection of optimum materials for robot, the design process is finished. The weight of the vehicle including the power source (batteries), on-board camera and computer controller along with other drive motors and actuators will approximately be around 1.8 kg. The dimensions of the robot while in operation are 0.275m in length, 0.2m in both width and height. The front part of the robot is designed in such a way that it gets inscribed in a circle perfectly during motion. To maintain perfect contact at all time the wheel positioning is very critical. Both the bottom wheels are place below the base of the robot to facilitate more space for other components such as power source, camera, controllers, sensors etc. The remaining three wheels are positioned perpendicular to each other on the actuator arm. The length of this arm can be varied using the linear actuator mechanism. In the present case this linear actuator mechanism is a simple rack-pinion mechanism. All the three arms are synchronised such that under operation the displacement of arms is equal in all directions. Four proximity sensors are used to calculate the distance between the surface of pipe and surface of the tyre. Three sensors are linked to one at each actuating arm in their respective direction. One sensor is linked to calculate the distance from surface of front tyre to the surface of the inspection panel. The three sensors on actuator arm are categorised into a single sensor unit (say sensor unit 1), while the other sensor (say sensor unit 2) is categorised separately. The categorised bill of the materials used is as follows Working of the robot Initially when the robot is at rest, all the three linear actuating arms are in contracted position. When the system of the robot is started, the sensor unit 1 present on the linear actuator arms calculates the distance between wheel and surface of pipe and sends the feedback to the on-board CPU. The CPU then sends a signal to increment the step motor to one step. This whole process of increment of steps continues until the wheel touches the surface of pipe and thus exerts a small normal force to grip onto that surface. Once this process is completed, drive motors of the robot are actuated. These motors are controlled by on-board CPU with the help of feedback from the sensor unit 2. All the five motors through a gear box connected to the wheels are powered with equal force, hence powering robot equally in all directions and sensor unit 1 ensures theres maximum grip available at the end of the actuating arms. The power to the motor is stopped once the sensor unit 2 senses the distance between the front wheels and the inspection panel is 0.2m, thus activating the camera to carry the inspection process. This whole process can be controlled using a manual operation panel or fully autonomous programmed GUI on-board. Simulation of vehicle dynamics The vehicle dynamics of the robot are established using specific equations for motion. This analysis is used to determine the performance capacity and capability of the robot. It also helps to calculate the velocity, force dynamics at any instance of time. Before using the equations a few assumptions are considered. The drag forces exerted on the body and wire are neglected. The drive force from the wheels is considered to be a constant ideal force, where wheel slip and wheel tyre deflection are neglected. The gravitational constant and the friction coefficient considered to remain constant throughout the process. The simulation emphasises more on the vehicle motion along the entire length of pipe including the inclined part of pipe. The terminology used for the following calculaitons are as follows Parameter Description Value mb Mass of robot 1.8 kg r Radius of the wheel 0.03m mw| mass of wire per unit length 0.2 kg/m Ub Coefficient of friction of body 0.5 Uw Coeffient of friction of wire 0.2 G Gravitational constant 9.81 m/s2 Ts Stall torque of motor 0.9 kg-m Wn No load speed of motor 38 rpm O Angle of inclination of pipe 40o Straight path A constant force is produced through five drive motors and is calculated as follows, where Fm is the force exerted by the motor, But the torque generated by the motor changes with velocity of the body. Torque at any time is given as Where w is rotational speed at that instant of time.

The Turbidity Test for Pasteurized Milk

The Turbidity Test for Pasteurized Milk Milk and dairy products, such as cream and yoghurt, are an important food group in the food pyramid. This food group provides us with calcium, which is not only crucial in strengthening our bones, but also important in many biological processes, such as facilitating the release of neurotransmitters that transmit nerve impulses across a synapse. Since dairy products serve such importance in our diet, dairy products manufacturing industry takes extra precaution in ensuring that these products meet the guidelines set by statutory bodies, one of which is that the maximum lactic acid content allowed in milk is 0.15% w/w. Hence, the industry will employ various methods to determine the quality of milk. As such, in order to better understand these industrial methods, 2 groups of experiments relating to titratable acidity (TA) of selected foods and turbidity test for pasteurized, UHT and sterilized milk were carried out. The titratable acidity test allows us to determine the titratable acidi ty of a sample as lactic acid (for dairy products) or citric acid (for lemon curd) equivalent. Basically, TA, as an acid equivalent, of a food product measures the total amount of that particular reference acid in the selected food. This reference acid is the major acid component, amongst all types of acid present in the food, which we want to quantify. TA is different from pH as pH only measures the [H+] dissociated from the acid molecules. Hence, TA is a more accurate measure of the degree of spoilage of dairy products than pH. The turbidity test however, serves a different function in terms of quality control. It is usually used by the industry to test if sterilized milk products have been sufficiently sterilized. Titratable Acidity of Selected Foods Materials Phenolphthalein as indicator 50.00ml burette 10.0ml graduated pipette White porcelain basin Magnetic stirrer Experiment 1: Titratable Acidity of Milk Pasteurized milk (Farmhouse Fresh Milk), expires on 20/9/12 UHT milk (Marigold UHT Full Cream), expires on 15/6/13 0.01M sodium hydroxide (actual concentration is 0.0107M) Experiment 2: Titratable Acidity of Cream Sour cream (Bulla Sour Cream), expires on 14/9/12 Yoghurt (FN Alive Yoghurt), expires on 11/9/12 0.1M sodium hydroxide (actual concentration is 0.105M) pH meter Experiment 3: Titratable Acidity of Lemon Curd Lemon curd (Waitrose lemon curd), expired on Feb 12 0.1M sodium hydroxide (actual concentration is 0.105M) Methods Titration of selected food products against NaOH of known concentrations were carried out in order to determine the titratable acidity of these food products. The titratable acidity in lactic acid or citric acid equivalent was then determined by via stoichiometric ratio of the acid to the amount of NaOH, as seen in the stoichiometric calculations below. 3 sets of titrations for 3 different groups of food products, mainly pasteurized milk and UHT milk, sour cream and yoghurt, and lemon curd, were carried. Experiment 1: Titratable Acidity of Milk 10.0 ml of pasteurized milk was transferred to a white porcelain basin. 1.0 ml of phenolphthalein indicator was then added to this sample. The burette was filled up with 0.01M NaOH and then titrated against the pasteurized milk sample. End-point of titration was identified when a pale pink colouration persisted for at least 10 s. Initial and final burette readings were recorded in Table 1 below. The procedure was repeated thrice for both pasteurized and UHT milk. Experiment 2: Titratable Acidity of Cream 10.00 g of sour cream was transferred to a white porcelain basin. 10.0 ml of water was added to the sample and mixed and pH was then measured. 1.0 ml of phenolphthalein indicator was added to the diluted sample. The burette was filled up with 0.1M NaOH and then titrated against the sour cream sample. End-point of titration was identified when a pale pink colouration persisted for at least 10 s. Initial and final burette readings were recorded in Table 2 below. The procedure was repeated thrice for both sour cream and yoghurt. Experiment 3: Titratable Acidity of Lemon Curd 10.00 g of lemon curd was transferred to a white porcelain basin. 10.0 ml of water was added to the sample and mixed. 1.0 ml of phenolphthalein indicator was added to the diluted sample. The burette was filled up with 0.1M NaOH and then titrated against the lemon curd sample. End-point of titration was identified when a pale pink colouration persisted for at least 10 s. Initial and final burette readings were recorded in Table 3 below. The procedure was repeated two more times.

As such, both samples are deemed safe for consumption. The titratable acidity of pasteurized milk is also observed to be slightly above that of UHT milk by a very minute concentration of 0.001 g/100mL. This suggests that pasteurized milk contains slightly more microbes than UHT milk, which goes in tandem with the properties of pasteurized milk. This is because pasteurized milk is heated to about 65oC for at least 30 minutes in order to preserve the flavor of milk, while UHT milk is heated at 135oC for about 2 seconds6. Hence, fewer microbes are killed in pasteurized milk than UHT milk. As such, pasteurized milk will have slightly higher lactic acid concentration which is produced from the fermentation of lactose by microbes. However, the magnitude of difference of 0.001 g/100mL obtained from the titration results is too small to make the above conclusive deduction. The average vol. of NaOH used is almost identical for both milk samples as there is only a difference of 0.05 ml, making the titration results somewhat anomalous. The main reason for this anomaly is the subjectivity of the end-point of titration. The colour change of phenolphthalein from colourless to pale pink is very difficult to ascertain by naked eye for the inexperienced, unlike workers in this industry who carry out large volumes of titrations every day. As such, the faint pink that I observed in pasteurized milk is most probably not the true end-point of titration or it could be that the faint pink I observed in UHT milk is over the end-point of titration for UHT milk.

This is because lactic acid is an organic acid and hence it is a weak acid. As such, lactic acid only partially dissociates, giving a [H+] that is lower than the total lactic acid concentration. This is due to the low acid dissociation constant, Ka, of lactic acid. However, by proportionality, it is observed that higher concentrations of lactic acid molecules will give a higher deprotonated [H+]. This is observed in Table 2 where the lower pH of yoghurt corresponds to a higher average volume of NaOH required to neutralize the lactic acid present. In addition, another observation is that yoghurt requires more than twice the volume of 0.1M NaOH to neutralize the lactic acid present as compared to sour cream even though yoghurt is lower in pH by 0.11. This is mainly attributed to the presence of probiotics added into yoghurt. As such, this means that more lactose in yoghurt is converted into lactic acid, resulting in the marked difference in average vol. of NaOH required for neutralization. This second observation also proves that pH is not a true measure of total lactic acid content in dairy products as this small difference in pH is accompanied by a larger than proportionate difference in volume of NaOH required for neutralization.

Hence, it can be deduced that this sample of lemon curd has passed the quality control measure. Citric acid is used as the reference for quality control of lemon curd mainly because citric acid is present in the largest quantity in lemons. Hence, measuring citric acid concentration present will be a good measure of the quality of the lemon curd. As such, this is a quality lemon curd sample. Even though this lemon curd product expired on February 2012, the citric acid content should not be significantly affected by microbial decomposition mainly because the acidic environment due to citric acid is not suitable for most bacteria to thrive. Discussion There are a few experimental procedures which can be improved on. Firstly, as mentioned in the results of experiment 1, the faint pink observed to mark the end-point of titration is subject to a large margin of human error. As such, a better method to solve the issue of colour subjectivity is to use a colorimeter to determine an intensity of pink as the end-point of titration, thus eliminating any inaccuracies that result from human error. Secondly, it was observed that the dilution of products of a more viscous consistency, such as sour cream and lemon curd, did not yield a homogenous consistency as compared with the milk samples and yoghurt. As such, the titrated NaOH may not have actually reacted with all the acid molecules as some acid molecules may be trapped inside the granular particles. This can be overcome by vortexing the cream and water mixture in a sealed round-bottom conical flask to ensure a homogenous solution is obtained, allowing us to obtain more accurate titration results. Thirdly, for runny liquid samples such as milk, there is a risk of spillage due to splashing when the magnetic stirrer operates probably due to the large exposed opening of the porcelain basin. Splashing can be overcome by using a conical flask to contain the samples and place a white tile under the conical flask so that the change in colour of milk can be made more obvious. This is because a conical flask has a much narrower neck and therefore a significantly narrower opening, thus minimizing spillage from splashing. In this way, more accurate titration results can be obtained. For lemon curd, simply measuring the citric acid concentration is insufficient to conclude a quality product. This is mainly due to the possibility of adulteration of lemon curd by adding more citric acid chemical, just like how milk was adulterated by the adding melamine. As such, additional qualitative methods can be employed, such as measuring the concentration of certain chemical substances more unique to lemon, such as limonene. Turbidity test for pasteurized, UHT and sterilized milk Materials Ammonium sulphate powder Pasteurized milk UHT milk Sterilized milk Method 4.0g of ammonium sulphate, (NH4)2SO4, was dissolved in 20.0 ml of pasteurized milk. The mixture was allowed to stand for at least 5 min and subsequently filtered. 5 ml of the filtrate was collected in a test-tube and then placed in boiling water bath for at least 5 min. The test-tube containing filtrate was then cooled in cold water and the contents were examined for presence of turbidity. Results Discussion Table 4: Turbidity test results Sample Observation Pasteurized milk A cloudy pale yellow solution with precipitation was observed. UHT milk A cloudy pale yellow solution was observed. Sterilized milk A clear pale yellow solution was observed. The turbidity test is useful in telling us if a sample of milk is sufficiently sterilized, whereby a clear solution will be observed. The turbidity test is first carried out by adding a denaturing agent, usually ammonium sulphate, (NH4)2SO4, to the milk sample. As NH4+ exhibits acidic properties, as shown in the following equation, NH4+ + H2O Ã   NH3 + H3O+ this addition of ammonium ions will bring about an increase in [H+], resulting in the disruption of casein micelle structure. This causes casein proteins to precipitate and coagulate as they interact with the ammonium and sulphate ions. For those casein and whey proteins that are already denatured by heat treatment during processing, ammonium and sulphate ions will form interactions with the charged R-groups of the acidic and basic amino acid residues, causing them to precipitate out of the solution. These precipitate are obtained as the residue from filtration. The filtrate obtained contains mostly undenatured whey proteins and probably some unprecipitated protein molecules encapsulated in the casein micelle structure amidst a solution of ammonium sulphate and other soluble milk products such as lactose. Upon heat treatment in a 100oC water bath, the milk proteins denature and are thus exposed to ammonium sulphate. They undergo the same mode of action with ammonium sulphate as described above, resulting in the observed precipitation. Referring to AVA regulations, pasteurised milk is defined to be milk that has been subjected to a single heat-treatment of 62.8 65.6oC for at least 30 min or 72 73.5oC for at least 15 s; UHT milk is defined as milk that has been heated at a temperature of at least 135oC for at least 2 s; sterilized milk is milk heated to 100oC long enough to sufficiently kill all microbes. As such, sterilized milk will have all the casein and whey proteins fully denatured and free in the milk due to prolonged heating. Whereas UHT milk will have a slight concentration of undenatured proteins present due to a short high heat treatment. For pasteurized milk however, it will contain the highest concentration of undenatured proteins due to lowest heat treatment temperature. Hence, the experimental observation in Table 4 clearly fits the hypothesis. On a side note, the yellow pale solution observed is most likely due to the Maillard reaction between lactose in and amino compounds in milk. Conclusion Titratable acidity and the turbidity test for milk is but only 2 out of the many methods that the milk processing industry employs to ensure that the heat treatments have produced milk that are safe for human consumption. The main disadvantage that lies with milk treated with higher heat processes is the loss of flavour. The nutrients that are lost during heat are usually replaced (e.g. enriched milk) and hence this is less of a concern for milk. As such, it is the companys decision on whether to process milk with an emphasis on taste or shelf-life. Nevertheless, it is of utmost importance that the milk products remain well within the margin of safety as stated by regulations. At the same time, regulatory bodies need to stay alert and play a part in ensuring that companies follow the safety guidelines, less an incident like the adulteration of dairy products through melamine addition may occur again.

Technology in the Classroom Stimulates Learning Essay -- Education Sch

Technology in the classroom, is it good or bad? I think this is a question that will be debated for many years to come. There are those who believe that we must have technology in the classroom so that we can move forward as a society. In a speech given by Roy Pea and Larry Cuban, Roy Pea quotes the Labor Secretary’s Commission on the Achieving Necessary Skill, or SCANS, as saying â€Å"Those unable to use technology face a life time of menial work.† Others believe that technology replaces learning and is actually making us stupid. Some believe that the costs out weigh the benefits and others who believe the opposite. I believe that technology in the classroom can only help to enhance and stimulate learning and prepare students for the future. The government has even acknowledged the need for technology in the classroom. In the â€Å"no child left behind† bill there is a section that covers this very topic. This section is known as the â€Å"Enhancing Education Through Technology act of 2001†. â€Å"The primary goal of this part is to improve student academic achievement through the use of technology in elementary schools and secondary schools.† Technology is everywhere and as educators of future generations we cannot simply ignore it or its influence in our daily lives. The world of education is constantly changing. The demands on teachers and students are ever increasing. Students are being expected to learn harder math concepts earlier in their educational careers. For example, my son is taking Pre-Algebra in the seventh grade. Without the use of technology, how can we expect teachers and students to keep up with these demands? Technology can allow teachers to provide their students with visual examples of concepts they ar... ...ts to develop marketable jobs skills. They are learning how to use technology to get the most from their education. We are preparing our students for the future and all the changes it will bring. Kathleen Patrice Gulley wrote â€Å"Given the role that education plays in preparing students to go into the world, it seems clear that there should be a connection between the world and the classroom. Unless education reflects the world in which it exists, it has no relevance for the students.† If we do not incorporate technology into our classrooms we are failing to give our children the best possible education and the skills necessary to be successful in the future.

Scarlet Letter Essay -- Literary Analysis, Hawthorne

Weak and powerless are so me of the words that describe women’s role in Puritan society. Men were the breadwinners and women were confined to the household. Most women lived their lives under the authority of men, but because of her unusual place in society Hester was able to overcome this. In The Scarlet Letter, Nathaniel Hawthorne switches the typical male and female roles to prove that when given the opportunity, women can be strong and independent members of society. Hawthorne uses Hester’s reaction to her punishment of wearing the letter A, to show women can survive in society without being dependent on men. Additionally, Hawthorne uses Hester’s relationship with Chillingworth and Puritan authorities to represent how women can be dominant. Furthermore, Hawthorne breaks down normal gender characteristics by switching the typical male and female traits of the characters in the novel. Because Hester was able to take care of herself and Pearl socially and economically as a single mother, Hawthorne proves that women can survive in society without being dependent on men. Hawthorne states â€Å"The tendency of her fate and fortunes had been to set her free. The scarlet letter was her passport into regions where other women dared not tread† (137). Hester was an outsider in her community and was able to look at society and the world with a unique point of view. Unlike most women during the seventeenth century, Hester was not confined to the household and was not under the authority of a husband. Hester defies the stereotype that women are weak and frail and cannot survive on their own. Because Hester does not have a husband to provide for her and Pearl, she is forced to provide for her family economically. â€Å"She possessed an art that suf... ...y become active members of society, just like men, if they are allowed to be gender neutral. Hawthorne breaks down normal gender characteristics by switching the typical male and female traits of the characters in the novel to prove that when society allows women to be gender neutral they can be just as important and able members of society as men. In The Scarlet Letter, Nathaniel Hawthorne uses Hester as a symbol of women’s liberation from male authority. Hawthorne believed women could be strong, independent and able members of society if only they were given the opportunity to prove themselves. Hester was a single mother that successfully provided for herself and her daughter and additionally stood up for herself when threatened by male authority. Hester is proof that when women are not under the restrictions of society they can be just as independent as men.

Humour and Satire in Urdu Literature

Humor and Satire In Urdu Literature Taken Gull* & Tableaus Abstract Humor & Satire are an integral part of all forms of literature; & when the tragic part of a drama/story becomes unbearable, humor/satire provide a much needed diversion & relief. This article examines the effect of humor & satire with reference to some of the leading men of letters of Urdu literature. Keywords: Humor, Satire, Urdu, Literature It is difficult for human beings to always lead a solemn and glum life. They require amusement, mental relaxation and recreation of some sort. Humor is the most suitable & Innocent option for this purpose.Humor can be verbal, visual or physical. Non-verbal forms of communication for example – music and art can also be humorous. Since literature is the replica of life it produces not only serious, subtle and delicate literary pieces but also the need for mild, mature and mellow compositions has always been longed for to coax and cajole the readers. To maintain the regulari ty and steadiness of life the elements of humor and satire are always needed. Prevalently humor and satire are used as a compound genre but they are two different words having two distinct meanings.Simon Waistlines is of the opinion hat humor is the weapon of unarmed people: it helps people who are oppressed to smile. In fact, humor succeeds where wisdom fails. Stephen Lacked asserts: â€Å"Humor may also be defined as the kindly contemplation of the Incongruities of life and the artistic expression thereof. I think this is the best I know, because I wrote it myself. † 1 This classification demonstrates three important aspects, which are the ‘Irregularities of life', ‘kindly contemplation' and ‘artistic expression'.The first point explains that a humorist does not look at the Irregularities Taken Gull, Assistant Professor, Zinnia College for Women, University of Appeaser. ** Tableaus laved, Lecturer, Zinnia College for Women, university of Appeaser. * Taken Gull & Tableaus Saved of life disdainfully rather gets amused with them, the second Is that he deals up with comic situations and gruesomeness of life and the third point explains that a humorist adopts a very skillful manner of portraying such funny situations instead of presenting them in a blunt and boring way.Moving on to the better half of humor that Is satire, sarcasm and gibe as defined by the encyclopedia Britannica; â€Å"Satire In Its literary aspect, may be defined as the expression In adequate terms of the sense of amusement or disgust excited by the ridiculous or unseemly, provided that literary form without humor, satire is invective; without literary form, it is mere clownish Jeering†2 Babul- al-Jeez Hafted Suicide defines satire in the following words: â€Å"The comic situations of life which can be pointed out and the contemptuous aspects of life which can be opposed and humorously criticized are termed as satire†. The process of sarcasm shares a lot w ith surgery. As a surgeon dissects and opens p the human body in order to extricate it by the infected portion, similarly a satirist identifies the follies of the society and extricates it of the corruptive matters. Although it is true and admitted that a satirist definitely has the gusto and ardor of elatedness and supremacy present in him. Whatever a satirist targets he shows his soreness towards it and is desirous to modify and aspire it. Perhaps the element of sympathy is absent which is considered to be the spirit of humor.ABA-AH-Chair considering, states: â€Å"Those satirists who extract amusement and laugh at the helplessness of people can never reach the heights. A good satirist is a merciless surgeon and ruthlessly dissects but in his satire there are no signs of personal revenge or hollowness. His sole purpose is constructive and to bring forward a positive change. The objective of his art is to point out the hideousness of life and to beautify society. â€Å"4 Whether it is satire or humor both require sincerity and fidelity, whereas, prejudice, priggishness and ego are all considered injurious for them.Making somebody a subject of humor or saturating someone on the basis of personal grudges is a complete violation of the rules and is The Dialogue 179 Volume VII Number 2 Humor and Satire in Urdu Literature extremely cheap in itself. That is the reason, why in every literature it is considered to be the humor and satire of the lowest degree. Contrary to this, the earnest pleasure or displeasure of mind and thought gives vitality to humor and satire. Then the most difficult aspect of this skill is to criticize your own self.To ridicule others and make them the target of buffoonery is comparatively easy but to mock at oneself jovially is most difficult thing in the world. It is therefore rightly said by Shabby-LU- Hosannas that only those nations are considered to be civilized who can make fun of their weaknesses. 5 Satire can only grow and develop in such societies where people have prudent and practical approach towards life. Only those people give space to satire who have the patience and will for change.Rehashed Mad Suicide says that humor and satire can only develop in those countries and nations who are independent and value independence. But this genre cannot build up among the nations who are bound in the shackles of slavery. Among the people where gods and decent and quality humor and satire. Sarcasm exposes before the readers the personal folly and humiliation of others which can only be handled by a mature mind of decent taste and disciplined attitude. In short, it is a genre whose reader is not only able to see the faults of others but their own misdeeds as well.The element of humor makes this genre light hearted, Jovial, intimate and infectious. It is therefore necessary that it should not be cheap and vulgar but should rather be meaningful, far reaching, universalism and enduring. In another situation humor and s atire can be made the basis for estimating standards of the literature of any language. Humor and fun are cultural and represent the customs, traditions, beliefs and norms of a particular society. In fact, the types of humor vary from people to people and society to society.The comic gestures and funny situations which can be a laughing stalk for us may not be humorous at all for a British or an American. On the other hand, according to Muhammad Alma Khan humor and satire together can create the history of the mentality of a nation and also are its heritage. Also it can be agreed upon that humor and irony of any community or civilization can be used as n absolute scale to test the glee, perception, temperaments and feelings of them. 7 Now we have to observe whether humor and satire are correlated or not.Norman Forlorn in this connection states that for literary satire two components are worthwhile; one is criticizing and saturating an odious incident or thing and the other humor. 18 0 Rasher Mad Quietude's opinion is contrary to that of Norman Furlong's. According to him satire is implicit in humor, whereas, humor should not be a part of satire. He considers humor superior to satire and a form of arts which is difficult in execution. For humor, he says: complacent attitude and conferment is required, whereas, for satire energy, sorrow, anger and assertion all are required simultaneously. In comparison to Rehashed Mad Suicide, Stayed Thatches Hussein's notion is comparatively more steady where he writes that the sour feeling that people develop while reading a satirical work is the very reason why people separate it from humor. Hence, Thicker and Meredith both have accepted the vitality of humor but not of satire. The reality is that the existence of satire is impossible without the presence of humor, whereas, humor can exist without attire. 9 Anyhow, it is important to observe the several techniques of humor and satire. ). The first technique is that of compari son in which humor is created by the simultaneously. The second technique is â€Å"the use of language†. Developing humor by creatively using the human speech and expression in which Taker (repetition), Rarity-e-leaflet (pun) and Bazaar Kanji (wit) are included . Iii). The third technique is that of a humorous situation. Iv). The fourth technique is the use of a humorous character. V). The fifth technique is that of parody. V'). The sixth technique s that of irony.No doubt there are other techniques like Sol-e-mammal (paradox), Ambulance (exaggeration) etc. But the ones given above are universally known and popular. After observing the general aspects of humor and satire, we switch on to the art of humor and satire in Urdu literature. When we throw a cursory glance at it we learn that the early onset of it can be found in some ancient Distant (legends). But the quality of humor and satire in some places is quite inferior while at others the jazzy effects of naturally pleasant and amusing humor and satire are visible. InUrdu literature humor and satire are conspicuously observed for the first time in the letters written by Kigali where frank humor and offhandedness are quite domineering. Kigali was blessed with dual attribute of being a poet and a prose writer. Humor was a part of his nature, that's why Hall called him â€Å"Hewn-e- Career† (humorous animal). His humor is pious and pure. He smiles at the occasions when people are whining and crying. He is capable of laughing at himself not only on others. In his 181 letters we find soft smiles instead of whole hearted laughter.In his letters, instead of sing loud and sharp colors, he uses a beautiful blend of light colors of humor. Besides Kigali, humor and wit are also observed in the writings of Sir Seed Mad Khan and Chablis Neumann, whereas, the elements of satire are more specific in the literature contributed by Deputy Nazi Mad. Sir Seed's work was serious, constructive and persuasive but in reaction the humor and satire of demeanor was introduced in the form of Owed-e-punch, which swathed the irregularities, serration and Jaggedness of the society.But the quality of humor and satire of this newspaper was below standard. Jaded Hussein, Mach Bag Steamfitter, Tarragon Nathan Hajji and Jaywalk Parsed Barb etc. Are the eminent figures of this age. After this, there were seen several different kinds of humor and satire in Urdu literature and it gained a lot of popularity, some were self evident while others were mellow and mild. The names of Mullah Ramirez, Rehashed Mad Squid, Pratfall Bag, Eczema Bag Caught, Patria Babushka, Shattuck Than and Flak BEMA, etc. Re worth seriousness and humor. His purpose is always serious but style of expression is pleasant and witty. His choice of diction is the main reason of his successful writings ND he is an expert of using idiomatic and flowery language of Delhi. He loves antiquity and traditional people and is considered a conservative person. His style is productive and he talks about the improvement of society but never becomes dry and stringy. Weaker Gaga says that liveliness and vivacity are the main features of his style.In his writings certain happenings, characters and comparison are not used as tools to create laughter but words and sentences are constructed in such a pleasant way that they pleasantly touch the sensations of mind and heart. Such expressions automatically create smiles and one feels fresh and lively. 0 Although Patria Babushka has less contribution (in volume) but whatever he wrote gives him a prominent place in Urdu literature. His study is very vast and he has a great appreciation & understanding of international and especially English literature.There is a touch of delicacy, liveliness and good taste in his humor. He creates humor with situations more than words. He is good at parody writing but repartee is his special technique. He does not laugh at the individuals but at the groups and classes. Stayed Abdullah writes about him that the essence of his humor is based on integrity, uprightness ND sincerity more than sympathy and kindness. He dislikes and hates absurdities. He is a misanthropist and sometimes mocks himself. 11 182 Rehashed Mad Quietude's name is also mentioned along with Patria Babushka.Rehashed Mad was an alumni of Alight and taught there as a professor of Urdu literature. His essays are not easily comprehensible and intelligible because he keeps on referring to specific incidents and only those people can enjoy his writings who have deep knowledge in history, politics and literature.
